CHARLES E. \VEBER, OF SPRINGFIELD, ILLINOIS, ASSIGNOR OE ONE-HALF TOJOSEPH SCHNEIDER.

COMBINATION BOLT AND WASHER.

SPECIFICATION forming part of Letters Patent No. 462,752, dated November10, 1891.

Application filed February 28, 1891. Serial No. 383,314. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. \VEBER, a citizen of theUnited States,residing at Springfield, in the county of Sangamon, State of Illinois,have invented a new and useful Combination Bolt and Vasher, of which thefollowing is a specification.

My invention relates particularly to bolts and washers for use asking-bolts, T-bolts, top-prop bolts for vehicles, and other machinerybolts.

The purpose of my invention is to provide simple and eiTective means toprevent the washer from turning independently of the bolt, therebyloosening the tap on the bolt. This I accomplish by the mechanism shownin the accompanying drawings, of Which- Figure 1 is a side view of aT-bolt embodying my invention. Fig. 2 is a section on the line 2, andshows the washer in position on the bolt.

Similar letters in both figures indicate the same parts.

The bolt A is of ordinary construction, except that the threaded portionof the bolt has a longitudinal saw-cut a, dividing the bolt into twoprongs a. The washer B may be circular, as shown, or of any otherconvenient form, and is formed so as to leave on either side of thetransverse integral bar (7 openings, through each of which one prong aof the bolt passes, and when the Washer is in position on the bolt thetransverse bar b lies in the slot at and prevents the washer fromturning independently of the bolt. The tap C is of ordinaryconstruction, and screws up close against the washer, binding bothclosely together. It is obvious that the bolt and washer beinginterlocked neither the washer nor the bolt can turn to loosen the tap.

\Vhat I claim is- 1. In a combination bolt and washer, the bolt A,having a longitudinal saw-cut a and parallel threaded prongs a, incombination with a washer B, having a transverse bar 6, substantially asshown and described, and for the purpose stated.

2. In a combination bolt and washer, a

washer consisting of a disk or plate B, having perforations and anintegral transverse barb, in combination with the tap C and bolt havinga longitudinal saw cut a and parallel threaded prongs a, substantiallyas shown and described, and for the purpose stated.

3. As a new article of manufacture, a combination bolt and Washerconsisting of a bolt A, having a longitudinal saw-cut a and parallelthreaded prongs a, a washer having perforations and an integraltransverse bar I), and a tap C, substantially as shown and described,and for the purpose stated.

CHARLES E. WEBER.
